JAMES HAMMOND LYON, OF PITTSBURG, PENNSYLVANIA.

PORTABLE FURNACE.

Specification forming part of Letters Patent No. 101,893, dated April12, 1870.

To all whom it may concern:

Be it known that I, JAMES HAMMOND LYON, of Pittsburg, in the county ofAllegheny, and in the State of Pennsylvania, have invented certain newand useful Improvements in Flat- Iron Heater or Summer Furnace; and dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a flat-iron heater or summer furnace, which can be used either in astove or without it, as may be desired.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a side elevation, and Fig. 2 a plan view, of my furnace.Fig. 3 is a plan view of the bed of the furnace when not used in astove.

A represents a fire-grate in the shape of a basket, having holes a a inthe bottom, elongated slots b bin its sides along the lower edge, andholes e 6 near the upper rim. Below the holes e e, on the outside of thebasket A, are lugs or projections d 01, so that when the grate orfurnace is inserted in the hole of a stove or range said lugs will comeon the stove, preventing the grate from going too far down, so as tostop up the draft-holes e 0.

Two of these grates or furnaces being inserted in the holes of a stoveor range, a plate, B, is laid or attached to their top for the purposeof heating flat-irons. This plate may or may not be provided with lids0, so that cooking may be done on the same.

When it is desired to use the furnace without the stove, either in theroom or outdoors, I provide a raised platform or bed, D, with openings,over which the grates are placed to assist the upward draft.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the two grates A A, cover B, and stand D, allconstructed substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 3d day of March, 1870.

JAMES HAMMOND LYON.
